We investigate the incentive and the welfare implications of a merger when heterogeneous oligopolists compete both in process R&D and on the product market. We examine how a merger affects the output, investment, and profits of firms, whether firms have merger incentives, and, if so, whether...

We investigate the relationship between segregation and public spending from the viewpoint of theory on social identification by developing a model wherein ethnic minority assimilation and public goods provision are both endogenous. We first show the possibility of multiple equilibria with...

We investigate the role of firm heterogeneity in considering profitability and desirability of mergers in the international economy. Analysis shows that higher trade costs make only crossborder mergers profitable whereas larger firm heterogeneity is likely to increase both domestic and...

Workers become skilled by incurring the training costs. Introducing the above settings into a trade...

In order to examine the impacts of market size on entrepreneurship, we estimate a monopolistic competition model that involves entrepreneurial decision by using data on Japanese prefectures. Our results show that a larger market size measured by the population density leads to higher incentive...
